DIAGNOSING ESL LEARNERSâ VOCABULARY KNOWLEDGE THROUGH MEMORY STRATEGIES
Purpose of the study: The present study diagnoses the vocabulary knowledge employed by ESL learnersâ through memory strategies. Schmiitâs (1990) Taxonomy of Vocabulary Learning Strategies (VLS) questionnaire was adopted and administered to 93 ESL learners. In order to get authenticities about the ESL learnersâ memory strategies with vocabulary learning, semi-structured interviews were also conducted with 30 participants who completed the questionnaire. The result exposed the subsequent array of memory strategies used by ESL learners from the most frequent to the least frequent strategies, particularly findings revealed that âUse new word in sentencesâ, âStudy word with a pictorial representation of its Meaningâ, âConnect word to a personal experienceâ are most popular whereas âUse scales for gradable adjectivesâ, âRelating word to unrelated items (Peg method)â were least used memory strategies.
Methodology: Schmittâs Vocabulary Learning Strategies Questionnaire (VLSQ) (1997) was favored to diagnose the vocabulary knowledge through memory strategies of 93 ESL learners. Initially the responses were collected through Google Forms. Additionally, 30 ESL learners were randomly selected for interviews in accordance to reassure participantsâ comprehension of the subject matters.
Main Findings: The study finds effective result among 93 ESL learners in acquiring vocabulary knowledge while using memory strategies with the assistance of technological modalities. It also listed the most frequent and least frequent use of memory strategies in Schmittâs Vocabulary Learning Strategies Questionnaire (VLSQ) (1997).
Applications of this study: The present study is conducted in English Language Laboratory, where ESL learnersâ can be benefitted and the learners can use these memory strategies while learning a new vocabulary when encountering a word.
Novelty/Originality of this study: The existing technological modalities will assist the learners to correlate more effectively. Subject and language experts in the field can design the instructional materials and tools to assist ESL learners to improve vocabulary knowledge through memory strategies
TDMA- MAC Protocol based Energy- Potency for Periodic Sensing Applications in Wireless sensing Networks
Energy potency could be a major demand in wireless sensing element networks. Media Access management is one in every of the key areas wherever energy potency is achieved by planning such MAC protocol that's tuned to the necessities of the sensing element networks. Applications have different necessities and one MAC protocol can't be best TDMA-based MAC (TDMAC) protocol that is specially designed for such applications that need periodic sensing of the sensing element field. TDMAC organizes nodes into clusters. Nodes send their knowledge to their cluster head (CH) and CHs forward it to the bottom station. CHs removed from the bottom station use multi-hop communication by forwarding their knowledge to CHs nearer than themselves to the bottom station each put down-cluster and intra-cluster communication is only TDMA-based that effectively eliminates each inter cluster further as intra-cluster interference
High Performance Regulation at Wide Range of Speeds
This Paper presents a simplified computer program for the simulation of CSI fed 3-Phase IM drive controlled by means of vector based V/f control method using MATLAB/SIMULINK simulation software. The main features of this type of simulation program are simplicity, accuracy and efficiency in terms of computation time. This simulation program can be used to verify the system design, to study system dynamic behavior and to investigate steady state waveforms of the drive system. The feasibility, reliability of the system and the validity of the control method are proved by the simulation results. The CSI drive has so many features compared to VSI drives. In addition, symmetrical GTO, when used as switching device in the CSI, makes the drive particularly suitable for implementation at medium high voltage (4160V and up) levels and also can be useful for wide range of speed control applications(from below to above rated speed)
Assessing preoperative pain sensitivity predicts the postoperative analgesic requirement and recovery after total knee arthroplasty: a prospective study of 178 patients
Background
The aim of this article is to study the correlation between preoperative pain sensitivity and postoperative pain and analgesic requirements for patients undergoing primary total knee arthroplasty.
Methods
Between December 2018 and April 2019, the pain sensitivity of 178 consecutive patients undergoing primary total knee arthroplasty was assessed preoperatively with a digital algometer. The patients reported the VAS (visual analog scale) score at 3 instances of needle prick (phlebotomy, glucometer blood sugar, intradermal antibiotic test dose), during the range of movements and completed the Depression Anxiety Stress Scale score. Postoperative VAS score, analgesic requirement, and physiotherapy milestones were recorded in all these patients on day 0 to day 4.
Results
The average age of the patients was 64.13 years and 69.1% were females. Females had lower mean algometry values (56.12 ± 12.77 [standard deviation]) compared to males (71.09 ± 18.78 [standard deviation]) (P < .001). Higher Depression Anxiety Stress Scale correlated with lower algometry values (P < .001). The postoperative VAS score was 2.54 ± 0.59 on the day of surgery which increased to 3.27 ± 0.69 on day 1 after mobilization (P < .001) and reduced to 1.67 ± 0.62 on day 4. Low algometer score correlated with higher postoperative VAS score (P < .05), increased analgesic requirement, and opioid utilization (P < .001), delay in achieving an optimum range of movements (P < .001) and independent ambulation (P < .001).
Conclusion
Preoperative assessment of pain sensitivity predicts postoperative analgesic requirements and recovery. Patients with a lower pain threshold should be counseled preoperatively and also receive a better titration of analgesics perioperatively and prolonged physiotherapy
Image-guided multilevel vertebral osteotomies for en bloc resection of giant cell tumor of the thoracic spine: case report and description of operative technique
The use of frameless stereotactic navigation is gaining popularity in spinal surgery. Although initially used in the spine for placement of lumbar pedicle screws, this technology has expanded to facilitate placement of spinal instrumentation at virtually all spinal levels. While previous reports have described the utility of image guidance for placement of spinal instrumentation, its use in assisting with resection of complex spine tumors has not been extensively reported. Here we describe the use of frameless stereotaxy to guide a complex, four-level sagittal vertebral osteotomy for en bloc resection of a giant cell tumor involving the chest wall and thoracic spine
